8 ICN transport for mmWave Networks (KDDI)

Tokyo Institute of Technology (Tokyo Tech), Sony Corporation (Sony), Japan Radio Co. Ltd (JRC) and KDDI R&D
Laboratories Inc. (KDDI Labs) announced they have jointly developed and successfully implemented a
3
2
40 GHz and 60 GHz wave-based high-throughput wireless access network for large-scale data content
distribution. This system provides a way to introduce a high-throughput communication service to next-
4
generation networks using millimeter wave (mmWave) -based wireless systems. The system also enables
efficient use of the mmWave communication band, which is much less crowded than the wavebands below
6 GHz. The development partners will demonstrate their achievements through open experiments at the
Mobile Communication Workshop sponsored by The Institute of Electronics, Information and
Communication Engineers (IEICE), held at Tokyo Tech on March 2-4, 2016. This development was conducted
as a part of the “R&D for Expansion of Radio Wave Resources” program sponsored by the Japanese Ministry
of Internal Affairs and Communications (MIC).

2 The 40 GHz wave band is a licensed band that is available for high-density applications in the fixed service defined in
ITU WRC-2000 (World Radio Communication Conference).
3 The 60 GHz wave band is an unlicensed band that can be used worldwide. In Japan, a band between 57 and 66 GHz
is available.
4 Millimeter waves are usually understood to be waves with operating frequencies above 30 GHz and wavelengths
that are measured in mm.
